DO RUN THE GROUND THROUGH THE CONCRETE! Take a look at the information on this site first though. You may be glad you did.

The prescribed / manufacturer's recommendation is to bolt a 3' straight formed extention at the base of each leg (total of 3), & to "suspend" these (a temporary wooden "cradle" will do admirably, as the cement sets) in a hole dug 4' square, & 4-1/2' deep --- the cement is to come but a few inches below the bottom legs of the actual tower section. Oh yes --- the bottom 1' of the square hole is to be "belled" outward a foot, or so. The documentation says this is good for heights of up to 64', or so...I've never gone beyond 48', & have never, EVER had an ounce of trouble in the two locations that I've had my tower up. BTW, the top of the tower as an old Cornell-Dubelier AR-44 rotator, & a 3-element Hy-Gain TH3 MkIII triband yagi... Use "industrial"-grade coarse cement, & do NOT run any ground leads through the block itself! ~73~ Eddy VE3CUI - VE3XZ ----- Original Message ----- From: "david knepper" <[EMAIL PROTECTED]> To: <[email protected]>; <[EMAIL PROTECTED]> Sent: Saturday, June 10, 2006 12:44 PM Subject: [AMRadio] Tower Construction > I am thinking about buying a stick of Rohn 55G in cement with about 3 > or 4 feet sticking out of the ground.
